# Advice to obtain a converged solution
|
|
|
|
In some situations it can be hard to obtain convergence with *Exo-REM*. The following advice are here to help you. They may not work all the time, so if you have any trouble left, you may want to send a mail to one of the maintainer.

Reminder: *Exo-REM* is not made to simulate highly-irradiated planets (equilibrium temperature > 2000 K) and non-H2 dominated atmopsheres (metallicity > 1000 times the solar metallicity).

- When searching for convergence, it is often useful to start any new run with your previously calculated temperature profile.
|
|
|
|
- Start with `eddy_mode = 'constant'` and `n_clouds = 0`. If you are far from convergence, you want to avoid any source of instability. You can always change these parameters once you have obtained an acceptable solution.
|
|
|
|
- Most of the time, you will need `n_non_adiabatic_iterations` to be > 0, and you always need to have `n_iterations` > `n_non_adiabatic_iterations`.
|
|
|
|
- At first, keep `retrieval_tolerance = 0`. This parameter can help you gain time when you make small changes in your simulation parameters, but using it is risky when you are far from convergence.
|
|
|
|
- Do not increase too much `retrieval_flux_error_bottom` and especially `retrieval_flux_error_top`. You risk to converge to a bad solution. |
